[0021] The present invention is further described below in conjunction with the specific implementation methods and the accompanying drawings. The accompanying drawings are only for illustrative purposes and are only schematic diagrams, not actual drawings, and should not be construed as limiting the present application. In order to better illustrate the embodiments of the present invention, some parts of the accompanying drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. It is understandable to those skilled in the art that some well-known structures and their descriptions in the accompanying drawings may be omitted.

[0022] The same or similar numbers in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "upper", "lower", "left", "right" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, it is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on the present application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0023] like Figure 1-5 As shown, a weighing type precipitation monitoring device includes a base 6, a mounting seat 5 is installed on the top of the base 6, a load-bearing seat 2 is installed on the top of the load-bearing seat 2, a weighing pan 10 is installed on the top of the load-bearing seat 2, and a weighing bucket is installed on the top of the weighing pan 10. Precipitation can fall into the water collecting bucket 9 for storage, and then the weighing pan 10 weighs the precipitation in the water collecting bucket 9 to obtain the weight of the precipitation.

[0024] The cross-section of the protective shell 1 is square, and a heat-insulating layer 8 is provided on the protective shell 1. The heat-insulating layer 8 can prevent the evaporation of the liquid in the device from being accelerated by the temperature. The electric slide rail 17 is fixedly arranged on the inner walls on both sides of the opposite sides of the protective shell 1. The top of the protective shell 1 is a closing structure and is connected with a circular tubular rain inlet 16. The rain inlet 16 protrudes from the top of the protective shell 1. The cross-sectional area of ​​the rain inlet 16 is used as a unit measurement area and needs to be accurately measured to ensure the accuracy of calculating the precipitation. A plurality of fastening bolts are provided around the mounting seat 5, and a fastening notch 25 is provided at the bottom of the protective shell 1. The fastening bolt passes through the fastening notch 25 and abuts against the protective shell 1. After the screw 7 is tightened, one end of the screw 7 will squeeze the protective shell 1 with the weighing seat, so that the protective shell 1 can be fixed on the load-bearing seat 2.

[0025] A funnel 21 is installed on the top of the water collecting barrel 9. The opening diameter of the top of the funnel 21 is larger than the diameter of the water collecting barrel 9, and can receive all the precipitation entering from the rain inlet 16. The opening diameter of the bottom of the funnel 21 is smaller than the diameter of the water collecting barrel 9, so that all the precipitation falling on the funnel 21 can enter the water collecting barrel 9, and the opening diameter of the bottom of the funnel 21 is much smaller than the diameter of the rain inlet 16. The precipitation entering the protective shell 1 from the rain inlet 16 can flow along the funnel 21 to the water collecting barrel 9. In the original technology, due to the large opening of the rain inlet 16, more liquid evaporation will occur, resulting in inaccurate measurement of precipitation. The opening diameter of the bottom of the funnel 21 is much smaller than the diameter of the rain inlet 16, and the contact surface between the water collecting barrel 9 and the outside world becomes smaller, so that the precipitation is not easily evaporated and lost after entering the water collecting barrel 9.

[0026] A conical plate 12 is provided at the lower part of the water collecting barrel 9, and a drain outlet is provided at the bottom of the water collecting barrel 9. A solenoid valve 11 is installed on the drain outlet, and a drainage pipe is installed at the drain outlet. The drainage pipe runs through the mounting seat 5. After each precipitation is completed, the solenoid valve 11 can be controlled to open to discharge the precipitation that has been measured. The precipitation in the water collecting barrel 9 can be discharged to the outside of the device through the drain outlet and the drainage pipe, so that there is enough space in the water collecting barrel 9 to measure the precipitation before each precipitation, avoiding insufficient space in the water collecting barrel 9, which causes precipitation to overflow from the water collecting barrel 9, and the drainage can be completed automatically, without the need for manual dumping after each precipitation, thus saving labor costs.

[0027] A mounting frame 14 is provided at the upper prismatic part of the protective shell 1, and a filter screen 15 is installed in cooperation with the mounting frame 14. The filter screen 15 can adsorb some solid particles and dust entrained in rainwater on the filter screen 15, and can filter solids such as leaves fallen from trees or in the wind to prevent impurities from entering the water collection bucket 9, which would affect the measured weight and cause deviations in precipitation measurement, resulting in too much deviation in the measurement results.

[0028] Electric slide rails 17 are respectively installed on both sides of the mounting frame 14, and a cleaning rod 18 is installed on the electric slide rail 17. A cleaning block 19 is installed at the bottom of the cleaning rod 18. The cleaning block 19 is made of rubber and has a certain plasticity. The cleaning rod 18 slides on the electric slide rail 17, thereby driving the cleaning block 19 to clean the impurities on the filter screen 15, which will prevent the filter screen 15 from being blocked due to the accumulation of impurities for a long time, so that the filter screen 15 cannot pass precipitation normally, resulting in inaccurate precipitation measurement.

[0029] A sewage outlet matched with the mounting frame 14 and the cleaning block 19 is provided in the middle of the protective shell 1, and the impurities pushed by the cleaning block 19 on the filter screen 15 can be discharged through the sewage outlet, and the sewage outlet is provided with a windshield, which is a rectangular shape with an opening at the bottom. The windshield can prevent the impurities from being affected by the external wind and being blown back into the protective shell 1, and a partition bar 20 matched with the cleaning block 19 and the sewage outlet is installed on the mounting frame 14, and the partition bar 20 can breed the liquid remaining on the filter screen 15 and discharge it from the sewage outlet, and one end of the partition bar 20 is connected to the sewage outlet, and the partition bar 20 is a long strip with a semicircular cross-section. When the cleaning block 19 pushes the impurities to the partition bar 20, the cleaning block 19 cannot directly send the impurities to the sewage outlet for discharge due to the installation accessories, but the cleaning block 19 can push the impurities to the top of the cleaning block 19, and the impurities can slide down along the slope of the partition bar 20, so that the impurities are discharged from the sewage outlet.

[0030] The weighing pan 10 is electrically connected to a controller 3, which can obtain the data measured by the weighing pan 10 through the controller 3, and then perform calculations to obtain precipitation data. The controller 3 is fixedly connected to a mounting base 5, and a flexible solar panel 4 is installed at the lower part of the mounting base. The flexible solar panel 4 can supply power to all electrical components on the device. The flexible solar wind energy panel 4 is bendable and foldable and can be directly attached to the outer wall of the rain barrel. Compared with ordinary solar panels, it can reduce the impact of wind on rainfall measurement, reduce construction difficulty, reduce engineering workload, and save construction costs. The weighing pan 10 can detect changes in gravity and can determine whether it is not raining by the change in gravity. When the pressure measured by the weighing pan 10 does not change within ten minutes, it is determined that it is not raining. The precipitation measured in the device can be discharged in the absence of rain to make room.

[0031] To sum up, in actual use, precipitation enters the protective shell 1 from the rain inlet 16, and after being filtered by the filter 15, it falls into the water collecting bucket 9 for measurement. After the precipitation is completed and the measurement is completed, the precipitation inside the water collecting bucket 9 is discharged through the drain outlet, and then the electric slide rail 17 is controlled to drive the cleaning block 19 to clean impurities through the cleaning rod 18, ensuring that the filter 15 can always pass the precipitation normally and be ready for the next measurement at any time.
